The evidence gathered by authorities including phone and online chat records shows that they made more than £300,000 from their fraud scheme. However, the officers believe it could be much higher , possibly more than £1million ($1.6m).

According to the National Crime Agency report, the fraudsters targeted innocent job hunters with fake job ads. Those who responded to the ads were sent a link via email asking them to complete an application form. Once the user clicks the link , it inadvertently install malware in victim's system.

The malware is capable of recording keystrokes and capturing victim's financial and personal data.

The compromised information is used by the fraudsters to get a new credit and debit cards, pin numbers.

The crooks will remain in custody and expected to be sentenced on Thursday 14 November.
